Flu - how long will it last?

I've been in bed since Monday and deteriorated into a distugusting mess with a four hourly paracetamol habit trying to sleep off the nightmare. I got laryngitis early on but it seems to be lifting finally, the sinuses on the other hand are not giving up - right side is causing pain in face and jaw. A tiger is helping. The worst is the constant nausea, I haven't been able to eat or drink much. I can't stand and just about stumble to the loo but DH is almost better (he hasn't been so ill) and threatening to go back to work - I have two kids and a school run which is tough normally due to other health problems. When will this end? It's like the worst hangover ever with a bad cold on top.

The fecking nausea is awful, I vomited and am struggling not to again. I really need a wash but would probably pass out.

I'm wondering if the GP might prescribe an anti sickness drug. My temp is much lower now and snot isn't such a luminous yellow anymore. But this nausea is intolerable, I have vomiting, almost to phobia levels and my wee is like orange juice Is the end in sight? Please....
